SPKN Insert Specification Guide
- S: Square shape, providing four cutting edges.
- P: Positive rake angle, which helps reduce cutting forces.
- K: Usually indicates a specific feature of the cutting edge or tolerance class.
- N: Often denotes the absence of a chip breaker or a particular nose radius.
Key features of SPKN insert
- Versatile, suitable for face milling and shoulder milling operations.
- Good balance between edge strength and sharpness.
- Effective for both roughing and finishing operations.
- Typically used for machining materials like steel, stainless steel, and cast iron.
- The positive rake angle can be beneficial for less rigid setups or challenging materials.
- Four cutting edges per insert, offering cost-effectiveness and extended use.
SPKN inserts are valued for their versatility and ability to perform well across various cutting conditions and materials. They’re designed to offer a good compromise between durability and cutting efficiency in milling applications.
